MEANS FOR COOLING CYLINDERS.

Application filed. February 25, 1907, Serial No. 359,149.

To all whom it may concern:

Be it known that I, GOVERNOR D. WARREN, a citizen of the United States,residing at- Denver, in the county of Denver and State of Colorado, haveinvented certain new and useful Improvements in lWIeans for CoolingCylinders, of which the following is a specification, reference beinghad therein to the accompanying drawing.

My invention relates to improvements in .means for cooling cylinders,and pertains more particularly to cooling air compressor cylinders.

In cooling cylinders in the old method, evaporation is impossible, and asutficient quantity of water must be supplied to the cylinder that itstemperature will reduce the cylinder heat by column only, while in myinvention I find by spraying a small quantity of Water on the upper faceof the cylinder and allowing it to flow downward in a thin film over theentire surface of the cylinder to the bottom, in the open atmosphere, itrequires a much smaller quantity of water as evaporation is used incooling the cylinders.

Another object of my invention is to provide a simple, cheap andeffective structure to accomplish the above result.

In the accompanying drawings, Figure 1, is a top plan view of acompressor cylinder showing my invention applied thereto. Fig. 2, is avertical sectional view taken on the line A-A of Fig. 1. Fig. 3, isan'enlarged end view of the cylinder heads showing the divisionalbridges in dotted lines. Fig. 4, is a transverse horizontal sectionalView taken on the line BB of Fig. 3. Fig. 5, is' a transverse horizontalsectional view taken on the line C-C of Fig. 3.

Referring now to the drawings, 1 represents the cylinders which, asshown, are of the compressor type of cylinder used in compressing air,although the same could as readily be applied to a pump cylinder or gasengine cylinder without departing from my invention. The cylinder 1 isprovided at its ends with the automatic air intake valves 2, and theupper end of the cylinder is provided with the compressed air dischargepassage 3 and pipe 4, all of which could be varied without departingfrom my invention.

The cylinder 1 's provided with the cyl- Specification of LettersPatent.

inder heads 5 and 6 which carry the intake valves 2 which may be .of anydesired structure or form, and are arranged to discharge the compressedair into the inner central spaces 7v which passes out through thepassages 3. The said cylinder heads, as shown, are provided with thetransverse bridge 8 which divides the cylinder heads into an inner airreceiving and conveying space 7 and the outer water receivingcompartment 10. The said compartment 10 is divided by the verticalbridge 11, the purpose of which will be hereinafter more fullydescribed. Each of the cylinder heads on opposite sides of the verticalbridge 11 is provided with a water supply pipe 12 and an outlet pipe 13,all of which will be hereinafter more fully described.

The cylinder 1 is completely surrounded by a casing 14 which has itsupper end 15 open to the outside atmosphere, while the heads 5 and 6 ofthe cylinder close the ends of the casing and form a water-tight acketsurrounding the cylinder, but the cylinder heads are not incommunication with the space between the cylinder and casing. A watersupply pipe 16 leads from any desired water supply and the same can besupplied with a pump for forcing the water thereto. The pipe 16 hasconnected thereto the two branch pipes 17 and 18. The pipe 17 extendsaround the cylinder and is connected to the water supply pipe 12 at theright of the bridge 11, and the water passing around the bridge 8 andengaging the valve casing keeps the valves comparatively cool and passesoutward through the pipe 13. The said pipe 13 extends upwardly andinwardly through the air intake passage 19 at one side of the cylinder,as shown at 20, and extends longitudinally of the cylinder at one sideof the center to a point adjacent the air intake 21 and has a closedend. The said pipe 20 in its lower face is provided with perforationsthrough which the water is sprayed upon one side of the cylinder. Thewater supply pipe 18 extends toward the opposite end of the cylinder andis likewise connected to the cylinder head 6 on the opposite side of thebridge 11 from that of the supply of the opposite head, so that thedischarge 22 on the head 6 will be on the same side as the inlet head 5.The discharge pipe 22 extends through the air intake 23 andlongitudinally of the cylinder on the opposite side fromthe pipe 20, andis arranged and constructed to spray the water thereon. The lower end ofthe casing 14.- has adischarge pipe 24: connected thereto, whereby thewater may be discharged from the casing as it runs off of the cylinder,and may be conveyed back to the. water supply, whereby it is used overand over again, thus enabling the use ,ofa

small amount of water to keep the cylinder cool.

In operation the water passes to the opposite ends of the cylinders, andenters one side of the heads, passing around the valves and out on theopposite side of the casing, and

is sprayed upon the cylinder, whereby the heads are kept cool and thewater by condensation keeps the periphery of the cylinder comparativelycool.

7 Having thus described my invention, what I claim and desire to secureby Letters Patent, is

1. The combination with a cylinder horizontally arranged, of means forpassing water through the heads, and then spraylng it upon the peripheryof the cylinderon opposite sides in the outside atmosphere.

.2. The combination with a cylinder, of a casing surrounding the same,and having an open upper side and a pipeextending across 1 the upperopen side of the casing, and discharging water upon the cylinder.

'3. The combination with a cylinder, of a I casing surrounding the sameand having an open upper side, and pipes extending across the upper openside of the casing and discharging .water upon opposite sides of thecylinder.
